Was I hacked: I just got wildclub and tried playing online but it won’t let me and I don’t play..

What do you mean it won’t let you play online? When you go to the main menu and press multiplayer, is it saying “Your data has been shared with other people too much.”? Or “Wrong data format provided.”? Or is it saying “Your data has been downloaded on another device.”? I can help if it’s any of those, but I can still try if it’s something else.
